Part 2 is configured. The conveyor belt 23 is an endless belt having a predetermined width, and is disposed on the outer periphery of the power pulley 11 located at a substantially central portion of the base T and the pair of pulleys 12 and 13 slidable by the oscillating mechanism 3 with respect to the upper surface of the base T. The conveyance path 21 is bridged so as to be vertical to form a substantially T-shaped conveyance path 21. The shape and arrangement of the transport path 21 are not particularly limited, but in this way, stable operation is possible with a compact configuration.

  2 and 3, the work discharge unit 5 is located on the opposite side of the work supply unit 4 with the power pulley 11 interposed therebetween, and is connected to a drive motor M as drive means disposed on the lower surface side of the base T. Yes. On the upper surface side of the base T, the gear 14 provided on the rotary shaft of the power pulley 11 meshes with the gear 15 provided on the rotary shaft of the drive motor M, and transmits the rotational driving force of the drive motor M to the power pulley 11. To do. Since the power pulley 11 is not directly connected to the drive motor M, the influence of vibration of the drive motor M can be reduced. On both sides of the power pulley 11, a pair of idle pulleys 16 and 17 are rotatably disposed outside the conveyance path 21, and guide a work gripping portion 22 attached to the conveyance belt 23. As shown in FIG. 1, when the power pulley 11 rotates at a constant speed in a certain direction (clockwise here), the conveyor belt 23 travels at a constant speed in the same direction.

  The work gripping part 22 has a base part that is attached to the outer surface of the transport belt 23 that becomes the transport path 21 at regular intervals, and a pair of claw-shaped chuck parts 221 that protrudes outward in the horizontal direction. The outer periphery of the intermediate part of the workpiece W is supported. The idle pulleys 16 and 17 each have a pair of upper and lower rotating plates that rotate integrally, and these rotating plates have a number of triangular grooves at opposing positions on the outer periphery. Each groove corresponds to the mounting interval of the workpiece gripping portion 22, and the base portion side of the workpiece gripping portion 22 is loosely fitted to align the chuck portion 221 holding the workpiece W at a predetermined interval.

  The oscillating mechanism 3 includes a slider portion 31 disposed inside the conveyance path 21 facing the workpiece supply portion 4, and a pair of pulleys 12 and 13 are rotatably connected to connecting portions 32 and 33 at both ends thereof. The oscillating drive unit 6 performs a sliding operation integrally. As schematically shown in FIG. 1, the oscillating drive unit 6 includes an oscillating lever 61, one end of which is coupled to the slider unit 31 for oscillating operation, an oscillating cam 62, a link member 63 that couples both, A connecting part 64 is provided. The link member 63 is provided with a connecting portion 64 on one end side, reciprocates in parallel with the slider portion 31 as the cam 62 rotates, and the other end of the swing lever 61 is connected to the other end side. The swing lever 61 is configured to be swingable around a fulcrum 611 at an intermediate portion, and one end side and the other end side perform a seesaw operation in opposite directions.

  FIG. 4 shows a detailed configuration example of the oscillating drive unit 6. One end side of the swing lever 61 is swingably attached to the support portion 65 fixed on the base T, and the connecting portion 64 integral with the link member 63. Is engaged with the outer periphery of the cam 62 for oscillating operation. The cam 62 is substantially elliptical and is provided integrally with the rotating shaft of the power pulley 11 below the gear 14. At this time, the rotation of the cam 62 causes the link member 63 to reciprocate via the connecting portion 64, thereby enabling the slider portion 31 to reciprocate (oscillate) in the same direction as or in the opposite direction to the transport direction. As shown in FIG. 2, a rail-shaped guide portion 35 is disposed on the lower surface side of the slider portion 31, and guides the slider portion 31 in the oscillating direction.

  As indicated by arrows in FIG. 5, the pair of pulleys 12 and 13 at both ends reciprocate integrally with the oscillating operation of the slider portion 31, so that the outer peripheral conveying belt 23 moves in a predetermined conveying direction. The position is shifted while feeding. That is, the transport unit 2 has a constant speed region where the transport belt 23 is transferred around the power pulley 11 at a constant speed, and a speed change region where the speed is increased or decreased by the oscillating operation. In the present invention, this oscillating operation is performed in synchronism with the feeding operation of the conveyor belt 23 by the power pulley 11 to create a pseudo stop region, the details of which will be described later. And the linear part between a pair of pulleys 12 and 13 used as a speed-change area | region is made to oppose the workpiece | work supply part 4, and when this linear part will be in a pseudo stop state, the workpiece | work W is supplied. Here, the workpiece supply unit 4 includes four rows of supply lanes 41 facing the conveyor belt 23, and transfers the workpiece W in the supply lane 41 to the workpiece gripping unit 22 in accordance with the oscillating operation. The conveyed work W is further transferred to the work discharge unit 5 and discharged.

  As shown in FIGS. 2 and 3, the workpiece supply unit 4 includes a workpiece storage unit 42 having a supply lane 41 as a workpiece supply path partitioned by a partition wall, and slides on a guide unit 43 disposed on a base T. Mounted movably. On the side of the guide portion 43, a work escape cam 44 is rotatably arranged. The cam 44 engages with a connecting portion 47 provided at the sliding portion of the work accommodating portion 42, and the workpiece accommodating portion 42 moves forward and backward with respect to the conveyance path 21 according to the cam 44 position. As shown in FIG. 4, the cam 44 has a substantially circular shape in which a part of the outer shape is cut out linearly, and the gear 18 provided integrally is a gear integrated with the power pulley 11 via the gear 19. 14 and mesh. FIG. 2 shows a state in which the notch portion of the cam 44 is located on the guide portion 43 side and the work accommodating portion 42 is moving forward (arrow in the figure).

  Therefore, the oscillating operation of the cam 62 connected to the power pulley 11 and the escape operation by the cam 44 can be synchronized, and the workpiece W can be supplied to the conveyance path 21 in the pseudo stop state. In the present embodiment, the workpiece supply unit 4 has a workpiece support member 45 inserted and disposed on the rear end side of the supply lane 41 so that the workpiece supply unit 4 can advance and retract along the guide rail 46. The workpiece support member 45 is driven by an actuator so as to advance following the workpiece supply operation. Although the workpiece | work W can be supplied stably by doing in this way, the workpiece | work support member 45 can also be abbreviate | omitted.

  The workpiece discharge unit 5 includes a rotating body 51 that is positioned in the vicinity of the conveyance belt 23 that passes around the power pulley 11. The rotating body 51 that rotates synchronously with the power pulley 11 is formed with a large number of substantially triangular work holding grooves 52 on the outer periphery at intervals corresponding to the work holding parts 22 of the conveyance path 2, and the work holding grooves 52 and the work holding parts 22. When is closest, the work W is transferred. A work cutout portion 53 is provided on the opposite side of the rotating body 51 from the power pulley 11, and is removed from the work holding groove 52 when the work W comes into contact therewith. In the present embodiment, the box-shaped workpiece receiving portion 54 is disposed below the workpiece cutting portion 53, but it may be configured to be conveyed to another process.

  As described above, according to the present invention, the workpiece W can be continuously conveyed at a high speed by combining the oscillating operation of the slider portion 31 with the conveyance path 21 running at a constant speed. This will be described with reference to FIGS. FIG. 6 schematically shows the oscillating operation of the slider 31. The pulleys 12 and 13 rotate at a constant speed following the power pulley 11 connected to the drive motor M, and the outer peripheral conveyor belt 23 is rotated. Is traveling at a constant speed (V). Here, when the cam 62 for oscillating operation connected to the power pulley 11 rotates and reciprocates the swing lever 61, the slider portion 31 between the pulleys 12 and 13 reciprocates and reciprocates. Depending on the shift direction, the conveyance speed changes. That is, when shifting in the same direction as the conveying direction (moving in the right direction in FIG. 6), the conveying speed increases, and the conveying belt speed (V) + oscillate speed (V) = 2V becomes the maximum speed. When shifting in the reverse direction (moving leftward in FIG. 6), the transport speed decreases and the minimum speed becomes transport belt speed (V) −oscillate speed (V) = 0.

  FIG. 7 shows the relationship between the feed speed of the conveyor belt 23 and the shift speed (pulley shift curve) of the slider portion 31 at this time. In the pulley shift curve, the speed becomes maximum during the return operation that shifts (L shift) in the direction opposite to the transport direction (feed direction of the transport belt 23), and becomes equal to the feed speed, thereby forming a pseudo stop region. In the shift in the transport direction (R shift), a double speed movement region is formed in the middle of the shift, and the portion delayed by the return operation is recovered. Therefore, as shown in FIG. 8, if the workpiece is supplied in the pseudo stop area at the minimum speed (0), it is not necessary to stop the transport unit 2. Therefore, unlike the conventional configuration shown in FIG. 15, the rotation control of the drive motor M that repeats running and stopping of the conveyor belt 23 is unnecessary, and the stop time of the conveyor belt 23 is shortened. Further, since the supply and conveyance of the workpiece W can be controlled by the cam operation synchronized with the continuously rotating drive motor M, the control is easy, and the time from supply to discharge can be greatly shortened and the speed can be increased.

  9 and 10A specifically show the relationship between the oscillating operation of the slider unit 31 and the workpiece supply. In (1) in the figure, the supply lane 41 of the workpiece supply unit 4 and the workpiece gripping unit 22 of the transport path 21 face each other with a gap in a state where the slider unit 31 is on the right end side. When the right shift end (1) is changed to the left shift by the oscillating operation, the facing position of the workpiece supply unit 4 becomes the closing position (2) where the workpiece supply unit 4 is stopped on the way to the left end side. FIG. 10B shows a state in which the slider portion 31 has moved from the right shift end (1) to the closing position (2). If the workpiece escape cam 44 is set so that the workpiece supply unit 4 performs the escape operation in accordance with this timing, the workpiece can be smoothly input (3) into the conveyance path 21 in the pseudo stop state. The slider portion 31 further moves to the left shift end (4), and then moves again to the right end side while the workpiece W is gripped by the workpiece gripping portion 22. In the middle of this, the double-speed movement region shown in FIG.

  Thereby, the workpiece supply from the workpiece supply unit 4 to the conveyance path 21 and the workpiece conveyance to the workpiece discharge unit 5 are performed at high speed without hindering the movement of the conveyance belt 23 toward the constant velocity region around the power pulley 11. be able to.

  FIG. 11 shows a second embodiment of the present invention, in which the configuration of the oscillation drive unit 6 is changed from that of the first embodiment. In this embodiment, instead of the oscillating operation cam 62 and the like in FIG. 1, a driving motor M1 as another driving means is provided to drive the oscillating mechanism 3. Other configurations of the continuous conveyance device 1 are the same as those in the first embodiment, and a description thereof will be omitted. The drive motor M1 is, for example, a servo motor having a servo mechanism. In this embodiment, the drive motor M1 is connected to the slider portion 31 of the oscillating mechanism 3 to control the oscillating operation. Also in this case, similarly to the first embodiment, by controlling the slider portion 31 to move along the pulley shift curve of FIG. 7, a pseudo stop region is formed in synchronization with the feeding operation of the conveyor belt 23. Can do. Therefore, the workpiece W can be continuously conveyed at a high speed from the workpiece supply unit 4 to the workpiece discharge unit 5 while the conveyance path 21 is running at a constant speed.

  FIG. 12 shows a third embodiment of the present invention, in which a continuous transfer device 1 ′ is provided that includes a work unit 7 for performing work other than work supply, instead of the work supply unit 4 of the first embodiment.

That is, by the oscillating mechanism 3, the work unit 7 is driven to perform the assembling operation at the time (2) when the facing position of the assembling unit 72 becomes the pseudo stop region, thereby continuously conveying the workpiece W, The process of performing the assembly work can be speeded up. Therefore, for example, the insulator of the spark plug illustrated in the first embodiment is used as the workpiece W, and the workpiece is fed into the continuous conveyance device 1 from the workpiece supply unit 4 and is conveyed in alignment, and then the continuous conveyance device 1 ′ of the present embodiment. Can be easily applied to the process of assembling parts such as a plug housing in the working unit 7. The same applies to processing (press-fitting, bending, etc.) and measurement work instead of assembly.
